Criminal psychologist David Hemswell receives a desperate call from a worried man. William Forbes, former solicitor to serial killer Jack Reid believes himself to be threatened by the living soul of the notorious Victorian enigma, Jack the Ripper.
Convinced that Reid was a descendant of the Ripper and that the evil that first entered the current era through the inheritance of the Ripper’s journal by psychiatrist Robert Cavendish, Forbes turns to Hemswell as his last hope to free himself from the demons he believes are pursuing him. Forbes travels to Skerries Rock, David Hemswell’s private island home off the bleak, barren west coast of Cape Wrath, Scotland, where Hemswell soon realises that there is much about his visitor that is disquieting and frightening.
Hemswell summons help in the form of paranormal investigator Kate Goddard, and together, the pair attempt to free Forbes of whatever strange phenomenon has assaulted his mind. As their investigation gathers pace, however, they soon begin to believe that the three of them are not alone on the tiny island. Has the soul of Jack the Ripper found a way to encroach upon the present day? Is William Forbes the living embodiment of The Ripper, or is he too a victim of the curse that appears to have been handed down across time by the unfortunate Cavendish family?
As time begins to run out, and the danger surrounding them grows ever stronger by the second, David Hemswell must face his own demons and is faced with the most terrible decision of his life, as the story that began with A Study in Red - The Secret Journal of Jack the Ripper and continued in Legacy of the Ripper reaches its shattering and terrifying conclusion!
